HELP ME WITH CAMS PLEASE

[Ansharky]

my last post outlines my build, Im doing a pi swap and getting -18 cc forged pistons on my 98 gt, it should be at or close to stock compression for a 99-04 gt. I’m decreasing compression from stock NPI block to future proof for trick flow heads and a centrifugal supercharger in the coming years.

While my build is still NA, I’d like to add cams for some nice even power. It’s still a daily so it should be streetable. Anyway I’m stuck between the MHS stage 2’s and the comps 262ah’s. The comps are more tested but I’ve heard good things about mhs.

Any advice?

Dont forget Crower, Howards, and most importantly (since you desire trickflow heads later on), dont forget trickflow for the cams you want.

Their are loads of engine, car, race type attributes that dictate possible cam selection for best performance. Calling upon any of the mentioned cam manufacturers above plus, mhs, modmax, mmr, Anderson ford motorsports, cushman cams is a good place to start.

Where i would not take build advice is BookFace. The true entrepreneurs of sn95 mustangs do not commun on FB.

Their is enough experience here on this forum that can suggest a good cam for your particular build. Any of the mentioned above have computer simulation software to help suggest a good camshaft more taylored to your build.

With all that said, let me ask. What is the intention of the car? Will it be mostly Street driven, race track, drag strip?

And this is why we need forums!! The wealth of knowledge like this !!!!

You have come to the right place brother. These guys know what they are talking about!

Dont forget the trick flow heads have the intake valve moved. They require a specifically ground cam. The PI cams don’t work correctly in the trick flow heads.

Also, your valve reliefs in the pistons need to match the trick flow heads.

For the next couple years while I get used to driving it again, it’s going to be an NA daily driver, hopefully with a little extra power. I’m rebuilding the engine and adding forged internals, with stock dimensions. I’ve also got a set of long tubes, h pipe with high flow cats, 3.73 gears, a built 4r70w from Darrin at BC auto, and a 10 inch torque converter from PTC.

After a couple of years of driving it after the rebuild, that’s when I plan to add the trick flow top end and a centrifugal supercharger of some sort, (just bullet proofing the bottom end for that right now because I have to rebuild it anyway) but for right now just looking to get around the 300 hp mark, make it a little more fun to drive.

If you are dead set on the trick flow cams, make sure you get the correct pistons now. Select your compression based on the trick flow chambers, and make sure they have the valve reliefs in the correct position.

If you get pistons catered toward the PI heads, they will not work correctly with the trick flow heads.

I would probably skip doing cams right now. Select those and install them with the new heads.

Maybe 300-350

Well when I do get the trick flow top end kit, I’ll get the cams that come with them, that’s in the future tho. Right now I’m just bullet proofing the bottom end for future purposes, that’s a good point about the pistons though, I hadn’t considered that, I thought the top end kit was designed to work with stock pistons.

Right now I just want cams to add a little power while I’m still running pi heads

The top end will work with stock pistons, if the cams are small enough. If the cams are large enough to require valve reliefs in the pistons, the regular pistons will not work.

I’d just really hate to see you have to buy something twice, or find out the hard/expensive way that something doesn’t work together.

Ah I see, thank you for clearing that up. So for right now I’m rebuilding my engine but I’m not doing the trick flow heads or forced induction for a couple of years, so the plan for the rebuild right now is to bullet proof the bottom end, and pi swap it. Before I add a ton of power I wanted to get used to the car again, but I wanted to add a cam with my other support mods to put me around the 300 hp mark while I’m running the pi heads.

I need to improve my driving skills before I start driving something with 400+ horsepower, cams were just an idea to wake up the engine a bit in the meantime.

Update: I’m not gonna do forged internal this rebuild, I’m gonna run the stock ones until it’s time for a lot more power. And I’m lost when it comes to suspension
